What are changes you've noticed since your TWA grew in length? What products can you not use anymore or have to start using because you have more hair? What techniques just don't work or did you have to start?

My hair is just above the shoulders and very thick and I'm getting tons of tangles. I feel like this was not happening when I had short hair. My routine is: 1. wash with conditioner (detangle with comb or brush) 2. apply leave-in 3. leave alone. What am I doing wrong?
